5 Using the manifold Display Mode Function Automatic mode If the automatic mode is activated, the testo 557 digital manifold automatically changes the display of the high and low pressure. This automatic change occurs when the pressure on the low-pressure side is 1 bar (15 psi) higher than the pressure on the high-pressure side. During the change, Load (2 s) is shown in the display. This mode is especially suited to air conditioning systems which cool and heat (heat pumps).
5 Using the manifold condensation temperature Co/tc are displayed after evaporation and condensation are complete. Zeotropes (refrigerants blends mix together) can separate from each other, unlike azeotropes which mix together to become one. Zeoptropes often blend refrigerants with different boiling points (saturation temps), where one will change from liquid to vapor before the other as they go through the evaporator.
5 Using the manifold Changeable - Evaporation Temperature (Ev) - Measured Temperature (T1) - Superheating (SH) Evaporation pressure Changeable - Condensation Temperature (Co) - Measured Temperature (T2) - Subcooling (SC) Condensation pressure With both NTC temperature probes connected, Δt is also shown. > Press [Mean/Min/Max]: to display min. / max. readings and mean values. Leak test / pressure drop test Systems can be tested for tightness with the temperaturecompensated leak test.
5 Using the manifold Duration of test Measured pressure beginning of test Differential pressure start compared to actual Actual measured pressure Vacuum measurement ✓ The vacuum probe is plugged into the front connection of the manifold and connected to the system. 1. Press [Mode] the vacuum mode is displayed. If ambient pressure is applied to the vacuum probe, then oooo is shown on the display. 2. Start the vacuum pump.
